OBJECTIVE To compare the effect of bronchodilator delivery by use of a metered-dose inhaler (MDI) or wet nebulizer on objective measurements of acute airflow obstruction in adult patients. METHODS Published and unpublished research was identified by MEDLINE searches for articles published from 1966 to 1994, review of scientific citations, review of article bibliographies, communication with e...

Maximal inspiratory pressure (MIP) is a marker for assessing the degree of respiratory muscle dysfunction. Muscle dysfunction represents a pathophysiological feature of chronic obstructive pulmonary disease. We aimed to determinate the MIP value in patients with airway obstruction, to evaluate the change in MIP with bronchodilator drug, and to show the relationship between the changes in MIP an...

This study describes the feasibility, repeatability, and interrater reliability of the measurement of airway resistance by the interrupter technique (Rint) in children 2-5 yrs of age, and examines whether reversibility to bronchodilator can be demonstrated in wheezy children. The mean of six Rint values was taken as a measurement. If subjects could complete one measurement and then a second 15 ...

BACKGROUND Few epidemiological studies have explored the relationship between orofacial clefts and bronchodilators. We assessed whether mothers who used bronchodilators during early pregnancy were at an increased risk of delivering infants with orofacial clefts. METHODS We used National Birth Defects Prevention Study case-control data from mothers of 2711 infants with orofacial clefts and 648...

BACKGROUND Bronchodilators such as long-acting muscarinic antagonists (LAMAs) and long-acting β2-agonists (LABAs) are central to the pharmacological management of COPD. Dual bronchodilation with umeclidinium/vilanterol (UMEC/VI; 62.5/25 μg) is a novel LAMA/LABA combination approved for maintenance treatment for patients with COPD. OBJECTIVE The objective of this study was to assess the cost-e...
